Fountain solution concentrates

Abstract

Liquid concentrate components of a fountain solution are provided, including a liquid film-forming fountain solution concentrate and a liquid surface-tension reducing fountain solution concentrate. The concentrates and water can be combined together to form a fountain solution composition.

1. A liquid surface-tension reducing precursor concentrate for a fountain solution, comprising:
 diluent at greater than 0% by wt to up to about 80% by wt selected from the group consisting of glycols and water-soluble glycol ethers, about 1–25% by wt solvent selected from the group consisting of partially water-soluble glycol ethers, esters, glycols, and alcohols, about 1–50% by wt nonionic surfactant, and water up to about 10% by wt, and excluding a film-forming polymer component. 
 
     
     
       2. The precursor concentrate of  claim 1 , wherein the surfactant is selected from the group consisting of acetylenic glycols, alkyl pyrollidones, propylene oxide/ethylene oxide block copolymers, alcohol ethoxylates, silanes, aryl ethoxylates, esters of fatty acids, and combinations thereof. 
     
     
       3. The precursor concentrate of  claim 1 , further comprising a biocide, dye, defoaming agent, dosage marker, or combination thereof. 
     
     
       4. The precursor concentrate of  claim 1 , further comprising an aromatic sulfonate, an alkyl sulfate, or a combination thereof. 
     
     
       5. A liquid surface-tension reducing precursor concentrate for a fountain solution, comprising:
 diluent at greater than 0% by wt to up to about 80% by wt selected from the group consisting of glycols and water-soluble glycol ethers, about 1–25% by wt solvent selected from the group consisting of partially water-soluble glycol ethers, esters, glycols, and alcohols, about 1–50% by wt surfactant, and water up to about 10% by wt, the water being derived from ingredient components, and excluding a film-forming polymer component. 
 
     
     
       6. A liquid film-forming precursor concentrate for a fountain solution, comprising:
 about 20–40% by wt sodium carboxymethyl cellulose; 
 about 20–30% by wt organic acid selected from the group consisting of gluconic acid, glycolic acid, and sulfamic acid; 
 about 10–20% by wt inorganic acid selected from the group consisting of phosphorous acid and nitric acid; 
 about 10–20% by wt buffering agent selected from the group consisting of organic amines and alkali compounds; 
 about 10–20% by wt water-soluble glycol solvent; and 
 water at less than 30% by wt; 
 the concentrate having a pH of about 3.5–5.5. 
 
     
     
       7. A liquid surface-tension reducing precursor concentrate for a fountain solution, comprising: about 30–40% by wt glycol, about 25–35% by wt water-soluble glycol ether, about 10–30% by wt nonionic surfactant, and about 5–20% by wt solvent selected from the group consisting of partially water-soluble glycol ether, ester, glycol, and alcohol. 
     
     
       8. A liquid surface-tension reducing precursor concentrate for a fountain solution, comprising:
 about 30–40% by wt ethylene glycol n-butyl ether; 
 about 25–35% by wt polyethylene glycol; 
 about 10–30% by wt nonionic surfactant selected from the group consisting of acetylenic glycols and alkyl pyrrolidones; and 
 about 5–20% by wt solvent selected from the group consisting of partially water-soluble glycol ethers and esters.
